Retired Justice Sandra Day O'Connor has officiated at the wedding of a gay couple at the Supreme Court, at least the second such ceremony at the court since its June decision that expanded federal recognition of same-sex marriage.

Justice Ruth Bader Ginsburg officiated at a weekend ceremony at the court in which two New Yorkers, including a former Ginsburg student at Columbia Law School, were married. Ginsburg has officiated at three same-sex weddings.
